The cutting method of the edge cutting device is generally to carry out laser cutting or die cutting along the edge of the touch layer. Because laser cutting or die cutting both have high precision requirements, after the edge trimming is completed, the touch The edge of the layer is prone to defects or residual black edges
When attaching the touch screen to the display screen, it is necessary to grasp the edge line of the touch layer for alignment. If the edge line is defective or excess black edges remain, it will affect the accuracy of the bonding, resulting in defective products

Abstract
The invention relates to a preparation method of a touch substrate and a touch screen. The touch layer is arranged on the substrate and is used for receiving a touch signal; the protective layer is arranged on the edge of the substrate and is used for limiting the edge cutting position of the substrate; wherein the protection layer comprises protection lines, and the protection lines are parallelto the side edges of the adjacent substrates; wherein the touch layer and the protective layer are disconnected. According to the touch substrate, the side boundary of the touch layer is prevented from being influenced during edge cutting, and the fitting precision of the touch screen and the display screen is improved, so that the yield of products is improved.
Description
technical field [0001] The invention relates to the technical field of edge trimming of a touch substrate, in particular to a method for preparing a touch substrate and a touch screen. Background technique [0002] In order to improve work efficiency, the touch layer on the touch screen is often obtained through large-scale operations. Multiple substrates are divided on a large board. After the touch layer is drawn on each substrate, multiple touch layers are obtained by cutting with an edge cutting device. Screen. The cutting method of the edge cutting device is generally to carry out laser cutting or die cutting along the edge of the touch layer. Because laser cutting or die cutting both have high precision requirements, after the edge trimming is completed, the touch The edge of the layer is prone to defects or residual black edges. When laminating the touch screen and the display, it is necessary to grasp the edge of the touch layer for alignment. If the edge has defec...
